SPECIFICATION forming part of Letters Patent No. 254,137, dated February 28, 1882. Application filed December 19, 1880. Nb model.)

To all whom z't may concern Be it known that we, WILLIAM E. J Moss and HENRY L. J AGOBS, citizens of the United States, residing at Columbus, in the county of Franklin and Statejof Ohio, havetinvented a new and useful Improvement in Road-Scrapers, of which the following is a specification.-

The nature of our invention consists, first, in a scraper-bowl provided with handle-loops of peculiar construction, through which the bandles may slide, and by which the handles may be fastened and held from sliding, as hereinafter described; second, in a scraper having sliding handles so arranged as to allow the bowl of the scraper to revolve with the handles through the bail.

Figure l in theaccompanyin g drawings is a perspective view of a road-scraper provided with our improvements and Figs. 2, 3, 4, 5, and 6 are side" elevation diagrams, showing the scraperin-five different positions in which it appears while it is filling with dirt and dumping the same.

A represents the bowl, B the handles, and G the bail, of a road-scraper.

The bail G, as usual, is hinged at a to the sides of the bowl; and the bowl B, as usual, is provided with a spur, D,which acts asa grab to takeinto the earth, and thereby insurearevolution of the bowl in the act of dumpiu g a load of dirt which has been collected by the bowl. This grabbing-spur is fastened to the upper portion of the back of the bowl, and it may be in the middle line of the bowl, or there may he two-such spurs-one on either side of such middle line of the bowl.

To the upper edge of each side of the bowl, and in rear of the pivot of the hinge a of the bail, an oblong loop, E, is applied, as shown. The loops E E are formed of strong plate metal bent into nearly an inverted'U form, so as to have bolting or riveting extensions e provided upon the portions which form the loops proper. The extensions care swaged or drawn down to the form of the inner and outer surfaces of the bowl at the portions where they bear against the bowl, and by this means the shoulders e are formed between the loops proper and their extensions 6. The loops E E thus formed are fastened to the scraper-bowl in any suitable manner--say by rivets or brazing material.

To the loops E E scraper-handles may be permanently fastened by inserting the ends of the handles into the loops and passing a suitable confining device through the sides of the loops and through the handle; but the greatest utility of the loops E E is developed when the handles B are constructed to slide in the loops, as shown in the drawings. The bandles,when constructed to slide, are formed with spurs b on theirinner ends, said spurs standing upward and at right angles, or nearly so, with the handles proper. The spurs b serve as stops to prevent the handles getting too far back and out of the loops, and they also serve for engaging with the earth during a certain stage of the operation of the scraper, as will be presently described.

Stop-pins b on the handles also serve to prevent the handles slipping out of the loops.

By referring to Fig. 2 it will be seen that the scraper is in an upright position, or ready for filling, the handles being set backward to their full length. In this position the scraper is drawn forward by its bail in the direction of the arrow until the bowl is filled and ready for dumping the'load. Now the handles with the bowl arelifted up, and with the aid of the team the bowl and handles are turned over, as shown in Fig. 3, and thus turned over the spurs on the handles engage in the earth, and the team being driven onward and the bowl drawn forward, the bowl and handles will occupy the positions shown in Fig. 4, and the handles can engage in the earth and turn over the bowl,-as

shown in Figs. 5 and 6, and thus turned over the scraper is drawn again to the place for fill: ing it with earth, and the operator takes hold of the handles and pulls them back untilthe spurs b strike the loops E, as shown in Fig. 2.

The handles may be drawn back by springs; but for simplicity in the construction of the scrapers we prefer to leave 011' such springs. So, also, might spring-catches be provided on the loops E or handles 13, for the purpose of making the handles permanent, instead of sliding, atsuch times as permanency in the handles may be desired.

The handle-loops form a simple, strong, and cheap fastening for stationary handles of scraper-bowls, and they also, in connection with sliding handles and a revolving honl, serve a very useful purpose, as has been set forth in this specification.

We have describedthebestmoleofconstructing the loops and other parts of our invention; but we do not limit ourselves to the special form of the parts.

What weolaim a ourinvention,and desire to secure by Letters Patent, is-
